Mehr zum Buch

The study focuses on the Cauvery River, essential for water, irrigation, and electricity across Karnataka, Tamil Nadu, and Kerala. It investigates the natural radioactive elements—uranium, thorium, and potassium—using a gamma ray spectrometer. Additionally, it categorizes river sand grain sizes as per USDA standards, including various types from gravel medium sand to clay. The research employs standard sieving and electromagnet techniques to separate samples for gamma ray spectroscopy analysis, highlighting the river's geological significance.
